In the second year of Jingkang, Bianjing fell, and the two emperors hunted north. The country of Zhao and Song Dynasty was like a candle in the wind. Li Shao, a member of the clan, was originally a marginalized royal relative. He was hiding in Jeju to avoid disaster. However, when the Jin army broke through the Jiangnan defense line, he accidentally took over the broken flag of King Qin's rebel army. Faced with the troubled times when Emperor Gaozong moved south to safety, the corpses of powerful ministers were left without food, and the rebel armies were fighting on their own, Li Shao took the motto of "restoring the Central Plains, returning the two emperors, and Qing Jun side" to gather the refugees, regulate the army, promote agriculture and mulberry, train new troops, and carve out a world between the Jianghuai River and the Huaihe River. He not only had to deal with the elite Jin army going south, but also had to deal with the suspicion and constraints of the Southern Song Dynasty court. He also had to compete for the leadership in reviving China in the Zhao Song clan, which was filled with nobles, as neither heir nor eldest son. This is a journey intertwined with power and iron-blood, and it is also a legend of a small man who used wisdom and courage to reshape the fate of the Song Dynasty and reverse the shame of Jingkang in the torrent of history. When partial peace becomes the consensus, there are always people willing to hold a lone sword and march northward, so that the battle flag with the word "Li" can fly over the hometown of Yanyun.
